CUMBTNATIQ'N (BRGAELSTOP ACTION.

Application filed September 4, 1920.

T all whom 2 2 may concern Be it known that JOHN T. Us'riri.

Zen of the United States. residing; at

ford. in the county of Hartford and Fatate of Connecticut. has invented certain new and useful Improvements in Combination Organ-Stop Actions. of which the 'tollowing is a specification.

This invention relates to combination organ stop actions. A type of such actions is shown in Letters Patent No. 1,279,492

issued to me F'lept. 24:. 1918 and to which reference may be had. I have number of motives in view among their. being the provision ct simple by which trace. constituting part of such an action. can be positively and accurately operated.

In the drawings accompanying and form ing part of the present specification l have shown in detail one of the several forms of embodiment of the invention which to enable those skilled in the art to practice'the same will be set forth fully in the following); description. Clearly I am not restricted to this disclosure. I may depart therefrom in several respects within the scope of the in vention defined by the claims following said description.

Referring to said drawings:

Figure 1 is a diagrammatic side elevation of combination organ stop mechanism involving the invention.

Figf2 is a longitudinal section of a 'LELlICh member.

Fig. 3 is a perspective view of part of an organ action equipped with stop mechanism involving the invention.

Fig. 4 is a detail in elevation on a slightly enlarged scale of the torward portion oi trace and a cooperative magnet.

Like characters refer to throughout the several views.

The organ stop mechanism to which I have referred in the patent hcreinbetore identified, involves a series of traces. One of these traces is shown and is denoted by 2. On its side are mounted a number of actuators as I call them. These actuators. tor purpose of clearness are not shown in the drawings. The trace 2 like its companions has an advance movement toward the right in Fig. 1 and a retractive movement obviously toward the left in this view. The means by which the advancing movement is effected, in. the present case constitutes one citilike p arts erial No. 408,216.

of the important features of the invention and is electrically brought about.

A trace which of course may be like any one of those shown and described in the Letters Patent to me. hereinbetore identified. is supported by the bed 3 which is channeled to receive the trace and others like it, for sliding movement. The trace 2 is advanced in the manner hereinbettore described and is retracted by a spring as 4: acting against it and also against the bed or base 3 and is customarily of wood.

As I have already observed the advancing cfi'ect oi th trace 2 is electrically accomplished and is desirably brought about by a magnet 5 of solenoid type, one terminal of the solenoid being connected by the wire 6 with the battery 7 constituting a suitable source of electrical energy. The wire 6 is connected to one pole oi": the battery, the wire 8 leading from the other pole thereof. to the switch 9 operated mechanically for instance by the button switch 10, the lever or equivalent part of the switch co-operating with a contact on the wire 11 which leads to the magnet 12. the wire 13 constituting a continnation of the wire leading from the magnet 12 to the terminal of the solenoid 5 opposite to that to which the wire 6 is connected. As shown the rock lever 16 is pivoted to a bearing 3' rising from the bed 3. Upon the closing of the switch 9 through the ac tion oi? the push button or equivalent part 10. the circuit involving the solenoid 5 and the electro-magnet is closed so as to energize bot-h iaguets.

The core or the electro-n'iagnet 5 is designoted by 14- and as shown is jointed to the link 15 which is pivotally connected at its outer end to the rock lever 16 mounted on the supporting structure or bed 3 and pivoted to the block 17 at the rear end of the rod or impeller 18. The impeller is advanced in the present case through the ac tion of the solenoid 5 and is retracted by th spring 19 actim respectively against the link 15 and block 17. The impeller 18 and other parts in tact are shown as occupying their back positions in. Fig. 1.

The trace 2 is shown as having at its forward end a notch 20the back and front walls of which have projections 21 and 22 respectively to enter cylindrical seats 23 and 24 in the ends of the cylindrical member 25 set into the notch or aperture 20. The back aperture 23 is of very much larger sine or diameter than the front aperture 2 1 in view of which circumstance. the rear portion ot the member 25 may be tipped up. This member 25 constitutes an armature :tor the electro-magnet 12.

The impeller 18 is shown (s havingta. toned to its forward lower side the operatingl' piece 26 of angular form in view of which circumstance the rod 18 becomes an actuator for the trace 2'. It the impelle 18 be advanced when the other parts are occupying; th position shown in Fig. l, nothing can be accon'iplishei'. It. however, the rear end of the cylindrical member be tipped up into the path ot the operating piece 26 it will be clear that the operating part 26 on the advance oi? the impeller 18 will engage the rear end of the cylindrical member and thus move the trace 2 forwardly.

Although for the sake ot simplicity only one trace is shown herein. it will be understood that in practice there are a group of these traces 2 and that there a magnet as 1.2 co-operative with each trace, the solenoid 5 however being common to a group or series of traces. it will be assumed that a trace is to be advanced. in this event the button will be manipulated to operate the switch lever 9 to close the circuit including the electro-magnet 12 and the solenoid 5. This draws the rear end of the member upwardly so that on the forward movement of the selected impeller 18 the operating piece 26 will strike the rear end. of the catch or cylindrical member 25 and thus advance the trace 2. On the deenergization of the solenoid 5 and magnet 12 by opening their circuit. the part 25 will of course drop and the spring 4: will return the trace 2 to its normal position and practically comrurrcntl the spring 19 will return the impeller 18 and parts associated therewith to their original positions.

l might say that upon the closing oi" a circuit. the armature 25 electrically acts very much quicker than the solenoid 5.

I have termed the part 19 l'n'oadly an actuator. Of course, the trace 2 in prai tice carries also what are known as actuators and which aresometimes known as cams. The part 18 can. therefore. he properly considered as an actuator because it does actuate or operate something else.

lVhat I claim is:

1. An organ stop action comprisin; a. trace. a magnet and its armature. the armature being" mounted on the trace. the map;- net when energized acting to attract its armature, an impeller acting on its advance. to'operate the armature when it is thus attracted by its magnet and means for advancing the impeller.

2. A combination organ stop action com prising a trace, an impeller a magnet and its ariamture the armature beingmounted on the trace and the n'iagnet when energized attractingits armature. an impeller on its advance engaging the armature when it is thus attracted. and advancing the trace. and electrical means for effecting the advance ot the imp ller.

Ii con'ihination organ stop action comprising; a trace, an impeller. a magnet and its armature. the armature being' mounted on the trace and the magnet when energized attracting its armature, the impeller on its advance engaging the armature when it is thus attracted. to advance the trace an electrically operated device associated. with the impeller and an electric cir uit including; the magnet and the electrically operated device. thecircuit when closed caus ng the cnergization ot the electrically operated de- Yice and the magnet, and the electrically operated device when energized acting to advance the impeller to etl ect the advance of the trace.
